Ultracold Fermions in a Graphene-Type Optical Lattice
Kean Loon Lee, Benoit Gremaud, Rui Han +2
Some important features of the graphene physics can be reproduced by loading ultracold fermionic atoms in a two-dimensional optical lattice with honeycomb symmetry and we address h…
Experimental observation of the Anderson transition with atomic matter waves
Julien Chabé, Gabriel Lemarié, Benoît Grémaud +3
We realize experimentally an atom-optics quantum chaotic system, the quasiperiodic kicked rotor, which is equivalent to a 3D disordered system, that allow us to demonstrate the And…
Coherent Backscattering of Light with Nonlinear Atomic Scatterers
Thomas Wellens, Benoit Gremaud, Dominique Delande +1
We study coherent backscattering of a monochromatic laser by a dilute gas of cold two-level atoms in the weakly nonlinear regime. The nonlinear response of the atoms results in a m…
Coherent backscattering of light by atoms in the saturated regime
T. Wellens, B. Gremaud, D. Delande +1
We present the first calculation of coherent backscattering with inelastic scattering by saturated atoms. We consider the scattering of a quasi-monochromatic laser pulse by two dis…
Quantum three body Coulomb problem in two dimensions
L. Hilico, B. Grémaud, T. Jonckheere +2
We study the three-body Coulomb problem in two dimensions and show how to calculate very accurately its quantum properties. The use of a convenient set of coordinates makes it poss…
